10. For redundant IMAMM03 master operation, connect an
NKAI01 cable from P4 of the NTAI02 to P1 of the NTAM01.
11. Slide the IMMAM03 into the MMU until the module is fully
seated and the faceplate is flush with the front of the rack.
Terminal Block Wiring
To connect field wiring, the terminal block covers must be
removed. Connect the wiring from the thermocouples to the TU
terminals. See Figure 2-3 for terminal block assignments and
wiring polarity. Field wiring should be 12 to 22 AWG wire.
Refer to the
Site Planning and Preparation
manual for infor-
mation on field wiring such as noise immunity and spacing
requirements.
To connect field wiring to the NTAI02, follow these steps:
1. Remove power from the cabinet.
2. Remove the terminal block covers.
3. Connect the thermocouple or millivolt wires to the terminal
blocks.
4. Replace the terminal block covers to maintain thermocou-
ple accuracy.
CAUTION
If input or output circuits are a shock hazard after disconnect-
ing system power at the power entry panel, then the door of the
cabinet containing these externally powered circuits must be
marked with a warning stating that multiple power sources
exist.
ATTENTION
Si des circuits d'entree ou de sortie sont alimentes a partir de
sources externes, ils presentent un risque de choc electrique
meme lorsque l'alimentation du systeme est debranchee du
panneau d'entree l'alimentation. Le cas echeant, un avertisse-
ment signalant la presence de sources d'alimentation multiples
doit etre appose sur la porte de l'armoire.
CAUTION
We strongly recommend turning off cabinet power before
doing any termination unit wiring. Failure to do so could result
in equipment damage. Do not apply power without verifying all
wire connections.
ATTENTION
Il est fortement recommande de debracher l'alimentation elec-
trique du cabinet avant d'effectuer tout connexion aux cartes
de raccordment des units. Des dommages aux equipments
pourraient survenir dans le cas contraire. Ne pas rebrancher
l'alimentation avant que toutes les connexions aient ete veri-
fiees.
